Title: Hydrodynamic drive device
IPC: F16H61/64
Filed: 1962-03-20
Abstract: 930,179. Hydraulic transmission of power. GENERAL MOTORS CORPORATION. March 20, 1962 [May 9, 1961], No. 10551/62. Class 69 (2). An hydrodynamic device, such as a coupling or torque converter, comprises an operating chamber from which the exhaust of liquid is controlled by a resilient ring 46 movable radially outwardly by the centrifugal force of the liquid in the chamber to open the exhaust. As applied to a torque converter, the ring, which may be of rubber or other elastic material, is disposed in a groove 44 in a circular member attached to a flange 17 connected to a driving shaft 14 and to a rear wall 19 carrying pump blades 31. The groove communicates with the working chamber of the converter through ports 42, 43 when the ring is urged outwardly by the centrifugal force of the liquid to connect the working chamber with an annular passage 41 leading to a sump 54. The ring can be urged radially inwards to close the ports by a controlled pressure applied to the ring through a pipe 86, the pressure being controlled either by a valve 64 operated by manual rotation of a cam-shaft 73 or by a valve 91 having a spool movable by a centrifugal governor 102 driven by gearing 103 from an output shaft 34 connected to the turbin 2  32. In operation, with the cam-shaft 73 in the position shown, fluid drawn from the sump 54 by a pump 57, driven by gearing 20 from the input shaft 14, passes through a pipe 58 and port 61 to exhaust 81 and no fluid is supplied to a pipe 82 leading through a cooler 83 to the working chamber or to the pipe 85, 86 leading to the groove 44 so that the ports 42, 43 are open and the working chamber of the converter is empty. When the shaft 73 is rotated, a quick rise portion 76 and an initial portion of a slow rise portion 77 move a member 72, the movement being transmitted by a spring 71 to the spool of the valve so that low pressure from a port 62 passes to the converter supply pipe 82 and from a port 63 to the pipe 86 to urge ring 46 inwardly to close ports 42, 43, the pressure acting against the centrifugal force of the liquid in the working chamber and being determined by the position of the cam which controls the biasing effect of the spring 71, whereby the opening and closing of the ports 42, 43 controls the liquid level in the converter. When the portion 78 of the cam is used, the spring holds the spool in a position maintaining full and constant pressure in the pipes 82, 86 so that the converter is maintained full. The constant pressure from the valve 64 to pipe 85 may be controlled by the governor 102 which actuates the valve 91 so as to reduce the supply to pipe 86 and permit the ring 46 to move outwardly during underspeed conditions to reduce the volume of fluid in the working chamber and unload the engine. During overspeed conditions, the governor opens the valve 91 so that pressure in pipe 86 maintains the ring in its inner position closing the ports 42, 43. The governor may be adjusted by moving an abutment 114.

Title: Improvements in or relating to method of and apparatus for applying bands to hollow cylindrical objects
IPC: B21K21/06
Filed: 1943-07-01
Abstract: 569,530. Shrinking hoops. BUDD MANUFACTURING CO., E. G. July 1, 1943, No. 10701. Convention date, May 2, 1942. [Class 83 (iv)] Driving bands are closed on projectiles by sectional dies contracted on the bands by bevel-closing means, the shell being supported internally by a loosely-fitting mandrel that permits elastic contraction of the shell body and consequent expansion when the pressure is removed, thus rendering the bands additionally secure. The projectile P is located on shoulders 44 of die sections 18 guided on radial ribs 35. Additional shoulders 46 locate the band B. Advance of a fluid-pressure ram 27 raises the base 31 supporting the dies which are retained by flanged members 37. As the dies and projectile rise, a bevel-closing ring 15 effects the contraction of the band. The mandrel 53 for supporting the projectile internally, has a stem 52 passing with clearance through the die sections and through a cone 48, spring influenced at 33 to cause opening of the dies on the descent of the ram. The slight float permitted to the mandrel takes care of any lack of concentricity of the parts.

Title: Control of polyphase alternating current motors
IPC: B66C13/26
Filed: 1945-04-30
Abstract: 590,982. Control of A.C. motors. IGRANIC ELECTRIC CO., Ltd. April 30, 1945, No. 10864. Convention date, April 28, 1944. [Class 38 (iii)] In a system for braking a polyphase motor by use of an auto-transformer to supply power to the motor primary with voltage unbalance, for high braking action, a reduced braking action is obtained by including impedance as well as the auto-transformer in the primary circuit. The invention is suitable for a drum controller or electromagnetic switches. As applied to a 3- phase slip-ring induction motor for hoisting, controlled by a hand-operated drum controller, movement of the controller through its hoisting positions connects the motor primary terminals to the supply terminals L1 L2 L3 and progressively short-circuits secondary resistance in the usual manner. In the first lowering position the terminal L, is connected (as in Fig. 2) to the midpoint of an auto-transformer 25 having one end connected to the motor primary terminal T1 and another tapping connected to terminal T3. The other end of the transformer is connected to terminal L3 and terminal T2 is connected to terminal L2. The voltages at terminals T1 T2 and T3 are represented respectively by 1, 02 and 03 in Fig. 2a. On the next and subsequent steps, impedances are progressively inserted between the transformer and terminal T1, to reverse the phase rotation by interchanging the phase relationship of vectors 01 and 03. Up to this stage the greater part of the secondary resistance is in circuit. On the next step a further impedance is connected between terminals L, and T, as in Fig. 5. Also the controller introduces all the secondary resistance into circuit. On the remaining steps the first impedances are disconnected and subsequently the last impedance is short circuited by a direct connection between terminals L3 and T, as shown in Fig. 7. On the first lowering step there is a small opposing (i.e. hoisting) torque at zero speed which increases with increase of speed as the load runs down. On the next step there is a very small lowering torque at zero speed and, on subsequent steps, a lowering torque which increases to full-load torque on the last step; in each case this lowering torque decreases and ultimately reverses with increase of speed. A brake releasing coil may be connected across terminals T, and T,. Fig. 1 (not shown) shows the connections to the drum controller for effecting the above steps ; during hoisting, the controller first closes the secondary circuit through all the starting resistance, next short-circuits part of the resistance in two phases and finally shortcircuits most of the resistance in all three phases. Specification 583,820 is referred to.

Abstract: 471,270. Microphones. SIEMENS BROS. & CO., Ltd., and SUTTON, G. W. April 17, 1936, No. 11075. Addition to 383,348. [Class 40 (iv)] In a two-electrode microphone or transmitter having a substantially rigid moving electrode coupled to a diaphragm by means of a light rod or pin and adapted to move as a whole in the granules in which it is immersed in such manner that its motion in either direction is opposed by granules, the front interior wall of the granule chamber has a substantially rigid outer portion adapted to provide a mechanical reaction against the movement of the granules which lie between the moving electrode and this wall and an inner portion composed of flexible non. resonant material forming an absorbing surface adapted to minimize the formation of unwanted standing waves in the granules and to assist in making the mechanical reaction to movement of the moving electrode more nearly the same for movements in either direction. As shown, the diaphragm 1, which is clamped between a casing member 4 and a spun-over ring 5, is connected by a rod 8 to a moving electrode 9, preferably of carbon, which is shaped so that a part of its surface is approximately parallel to the associated surface of a fixed electrode 12 formed with a central bore 20 and clamped to a brass member 22 forming one of the terminals of the microphone. The wall of the granule chamber is partly constituted by a brass member 17 having the outer part of its front wall of frusto-conical shape and formed with a hole closed by a composite washer 15 of a number of discs of Swiss silk. The washer 15 is clamped between the member 17 and an apertured brass disc 16 seated in a brass member 14 provided with a flanged portion 26 which is clamped between the member 4 and a threaded member 24 carrying an insulating block 23 in which is mounted the fixed electrode 12.

An explosive nut comprises nut-segments 72 releasably held in a retainer 88 by yielding means 98, and an explosive 47 for overcoming the means 98 and expelling the retainer from the segments when these are engaged on a bolt 71. Three nut-segments 72 are held in the retainer 88 by spring means or, as shown, a lip 98 on a screw-threaded cap 96 on the retainer. The explosive 47 in a bolt 101 may be inserted after the nut has been positioned. The part-cylindrical segments 72 are held against rotation in the retainer by keys 94 in keyways 77 formed in the adjacent edges of the segments. The keys are lodged in slots 97 in the end of the retainer and engaged by a yieldable flange 98 on a collar 96 which also prevents accidental escape of the segments. Upon firing the explosive, flange 98 yields adjacent the segments, allowing the retainer to be projected along the segments until the corners 95 of the keys 94 engage the ends 81 of the keyways. This tends to pivot the segments about the end of the bolt 71, effecting a positive release, and causes the rest of the flange 98 to yield so that the retainer may fly off the segments. The nut segments may be tapered, and release of the segments may be by fracture of the collar 96 or retainer.

Title: Process for the preparation of a substance with anti-peptic activity
IPC: C08B31/06
Filed: 1961-03-28
Abstract: Non-depolymerized starch, having intrinsic viscosity at least 0.3 (20 DEG C. in water) is obtained by dissolving starch in a heated aqueous solution containing electrolytes at pH8, and fractionating this solution with an organic water-miscible solvent e.g. methanol. The non-depolymerized high molecular weight fraction is then sulphated in presence of an organic base e.g. pyridine to a sulphur content of 16-19%, the resulting diester being separated as e.g. an alkali metal salt. In an example, maize starch is heated at 80-85 DEG C. in sodium hydroxide solution at pH8. A high molecular weight fraction of intrinsic viscosity 0.6 is precipitated by methanol, and is sulphated with pyridine and chlorosulphonic acid.  The product has anti-peptic activity without the anti-coagulant properties usually associated with sulphated polysaccharides.
